Hi, I have a Workcenter XD102. It gives me a J2 error. I don't know how to fix it. Please help. Thank you very much, Charles

J2 error for Workcenter XD102 indicates a Drum Cartridge Problem sensed by the main PWB indicating that the Drum cartridge had reached its end of life. You may replace the Drum cartridge with a brand new Drum Cartridge. This should fix the problem.
If you believe that its not the Drum cartridge with or without replacing the Drum cartridge, you may try to open the printer, make a good clean and perform the below. 1. Check the PWB and Drum Cartridge Reset Circuit for any loose connection and short circuit. You may re-seat the cables and terminations and test. 2. If that didn't work you might need to get some voltage from the Drum Cartridge Reset Circuit as per below. 2a. If voltage is more than 0.5 VDC measured between PJ CN116-2 and GND then you need to replace the Drum Cartridge Reset Switch PL x.x. 2b. If voltage is less than 0.5 VDC measured between PJ CN116-2 and GND then actuate the Drum cartridge Reset Switch. Then check the voltage if its +5 VDC measured between PJ CN116-2 and GND. i. If not then replace the Drum Cartridge Reset Switch PL 5.. ii. Else it should be fine. iii. If not then replace the Main PWB, PL 7.1.
